Run server upgrade in ipactl start/restart

During a distro upgrade, e.g. F-26 to F-27, networking may not
be available which will cause the upgrade to fail. Despite this
the IPA service can be subsequently restarted running new code
with old data.

This patch relies on the existing version-check cdoe to determine
when/if an upgrade is required and will do so during an ipactl
start or restart.

The upgrade is now run implicitly in the spec file and will
cause the server to be stopped after the package is installed
if the upgrade fails.
